rog_eye | Access ROG_EXT port on selected ASUS motherboards

rog_eye is a C++ library typically used in Internet of Things (IoT), Arduino applications. rog_eye has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

The Arduino's I2c Pins A5/PC5 (CLK) and A4/PC4 (DATA) plus a ENABLE A5/PC3/PIN 17 for pinmode, this pin is connected to the ROG_EXT pins 5(SDA),7(SCL),4(ENABLE) See Diagram rog_ext_bb.png bring ROG_ENABLE(pin 4/con1) high and the motherboard exsposes the internal i2c bus,. Anyway, so once ROG_ENABLE is HIGH then the arduino responds to I2C slave addres 0x4A, the motherboard writes to this at regular intervals, some values get updated more often Sometimes high cpu usage will delay updates, use avereaging for sensors that may jump large values if delayed. currently the Arduino device act's as a I2C memory write only device, two memory arrays up to Size(0xff) are available, one can be compare to the other for simple value change monitoring (CPU heavy, restrict to 0xf in size during comparison but full memory can be done) Data is written to the memory[MEM_SIZE] buffer, current set at MEM_SIZE=0xff. Address conversions Between Busppirate sniffer and Arduino I2C, Address 0x4A in arduino code with slave mode is seen as 0x94 write and 0x95 read on a buspirate sniff. Math on cpu voltage is known to be different, hence the CPU_TYPE define (host motherboard cpu not the arduino MCU device) QCode location also different between AMD and intel, possible reason is firmware limits of ROG_EXT device or OEM wanting to sell more panels like intel hide the fact motherboards can be compatible between generations. Rog Connector pinouts (see rog_ext_maximus image ). Asus Front Base Pins/Colours At Motherboard Side Functions supplied where possible,. On Actual Front_Base and OC/Panel units the system detects USB and switches to update mode , thats why manuals request you connect to normal USB pin header to update the devices. when USB A/B is missing the device switches to normal function.
